ASH GATE.

Application filed March30, 1926. Serial No. 98,570.

My invention relates to certain improvements in ash-gates used in discharging ashes from the hoppers of stoker fired boilers but it will be understood that the invention can be used in any type of ash-hopper as desired.

- ater is used to quench the ashes in the ash-hopper to hasten cooling, and as more water is used than the ashes absorb, there is a certain amount of water that should be carried away and not allowed to escape into the car or other conveying medium.

Furthermore, a certain amount of fines or silt will pass through the gate with the water, and this silt clogs the water-trough unless it is removed. 7

An object of my invention, therefore, is to provide means for carrying off the excess water from the gate, and to provide means for discharging the fines 0r silt that collects in the drip-trough.

In the accompanying drawing:

Fig. 1 is a sectional elevation of a portion of an ash-hopper illustrating my improved ash-gate; V

Fig. 2 is a face View of the gate;

' Fig. 3 is a view similar to Fig. 1, but show- 1 ing the gate in section and in'open position; and

Fig. 4 is an enlarged sectional view of the trough showing the scraper in osition.

The ash-hopper 1 has an inc ined bottom, and in the bottom is an opening 2. This opening is closed by a gate structure 3. Below the gate structure are tracks 4 for cars 5 shown by dotted lines in Fig. 1. While I have illustrated a track and cars as a conveying medium, any suitable type of conshown in Fig. 3, allows the ashes to flow,

from the hopper into. the car or other conveyor located directly below the gate.

The gate has a curved bod portion 9 and sides 10. I Trunnions 7, whic form the pivots, extend through bearings 11 in the frame 6, and have at their outer ends arms 12 on has an opening 18 at the opposite end.

The open end of the trough extends over one end of the drain 19, which has an inclined bottom and is provided with a discharge opening 20, so that any water passing from the trough into the drain will be discharged through the opening 20 into a gut V ter21 or other suitable receptacle.

On the trunnions 16 of the trough 17 are arms 22, which are connected by links 23 to arms 24 on the trunnions 7 of the gate, so that as the gate is moved into the open position, the trough is turned to the discharge position shown in Fig. 3.

Depending from the body 6 of the gate is a scraper 25, which is fixed in the present i11- stance and extends to the bottom of the water drip-trough. The bottom of the trough is rounded as shown so that as the troughis moved from the position shown in Fig. 1 to that shown in Fig. 3, any silt or fine material will be scraped from the drip-trough and will be discharged into the car or other receptacle, so that the trough is kept comparatively free for the escape of water through the drain- 1 I I claim 1. The combination with a gate structure including a frame and a gate pivotally mounted in said frame, of a bracket carried 'by the said structure on each side of said gate, a drip-trough disposed beneath said gate, said trough having trunnions mounted in said brackets, said trough bein inclined and'having the lower end thereo open, a scraper extending from the frame into the said trough, the lower edge of the scraper being inclined to correspond to the inclined bottom of said trough, and means connecting the gate and trough whereby said trough will be turned on its trunnions in unison with the turning of the gate on its axis.

.2. The conihiimtion with :1 gate structure including :1 frame and a gate pivotaily mounted in said frame, 11 flange depending from the frame and forming a scraper, a drip trough pivotally mounted beneath the said flange and carried by the said structure ilulepel'idently of (he gaie, Said scraper being disposed Within said trough, and means eonnesting the gate and trough whereby said trough will he turned in unison with the turning of the gate on the axis.
